My InStep is almost five years old and thousands of putts later it still looks new. Never leaving it outside likely helps. I added the inner chains using zip ties and a copper ring made of 8 gauge wire (outers were later replaced with the same, better chains).
I wanted the target diameter to more closely match regulation baskets so I used zip ties to draw the chains towards the middle, making the diameter five inches smaller. The catch basket is also raised about three inches by placing a PVC pipe spacer on top of the C-clasp. It's close enough now to regulation dimensions it can be used in an event need (like the last several weeks at Sugaw Creek Am League to stand in for stolen #11).
Because the basket is often used indoors, there's a PVC sleeve with target dots covering the pipe to dampen the sound. I can stand in the den and shoot 20-footers into the wash room and you can't hear it upstairs. I take the sleeve off when using outside.
